I notice on mine, its fine when im accelerating, but when I slow down, the speedometer is jumpy like it catches. Say I slow down 10 mph, it only moves down 8 mph. then I speed up again and slow down again and its off even more. One time my speedo was topped out at 130 on my truck and I was going 60. Ill check the wires and stuff. Where does this grease go?

it would go on the electical contacts. from the way your&#39;s sounds i would be checking the bushing in the tailshaft housing for excessive wear. unless all the needles are bouncing or reading erradically, i wouldn&#39;t think instrument panel ground. i&#39;d sure trace the wires back to the pcm just to be sure there are no shorts or bare spots on the wires. maybe hummertech knows other things to check. sounds like a common problem.
